Hello,

I have D945GCNL intel motherboard.

Using AIDA64 Stability test for 5-6 minute.
I found E6600 is taking max temperature 72 and E6700 temperature taking max temperature 80

Attached the images. Please check and suggset... is it fine to take more temperature for E6700 or processor is having issue.

Thanks

Rated tdps are an estimate and cpus are also grouped together depending on testing. It's physically impossible, unless you know how to break the laws of physics, to run a higher clock on the same exact architecture and specs and not have temps to run higher. However, temp did seem to increase more than expected. Even with the small stock cooler, I would have only expected a few degrees especially with vcore being the same. There could have been a difference in mounting or thermal paste application.

Edit: Looking at the pics more closely, the idle temps are also 10c higher. That would tell me possible cooler/tim or ambient temp differences. They idle at the same speeds and vcore so should be the same there. Even the mobo is idling...

There is only processing diff i.e. E6600 2.4Ghz and E6700 2.67Ghz.
But both processor has TDP 65W.

When I use E6700, fan rotation speed increase most of the time
While E6600 fan rotation seems normal.

I thought E6700 has some issue thats why it is increasing temperature due to which fan rotation increases.

But not sure..
